hi Guys, found this earlier, cant remember where i got the link but thought i'd post it here as one of you guys will probably get to use it before i do... anyway, they have a free mastering modular limiter and a compressor.... if someone fancies trying them out and reporting back how you find them, i've downloaded but im flat out with work for the next few days so will try when i get the chance.
